Trunk-extensor endurance (Biering-Sørensen) + McGill torso-balance ratio screen — Copenhagen, Denmark.

Screen for back pain first, then time the Biering-Sorensen and McGill hold tests for a Copenhagen worker. Trunk muscle endurance and balance are unmeasured, so any imbalance between the trunk muscles stays unknown.

Fund it for $220. The receipt lands onchain once the proof is approved.

What it looks like

On a firm mat, a person holds a side bridge while a partner times the hold with a stopwatch and records each side's time in a secure note.

Pay

$220 proposed

This job is not funded yet, so this figure is a proposed price, not money held for the worker. If a buyer funds it, approved proof settles that price onchain. If nobody funds it, approved proof earns provable credit toward the work instead of cash: recorded, and readable any time at vealth.net/labor/credit/(your wallet). You see which before you claim, never after.

Proof

pre-test back-pain screen cleared or routed + all four hold times recorded + extensor, flexor, side-bridge ratios computed + high-risk pattern routed to a clinician or PT + training plan recorded for those cleared

This is exactly what gets it approved. Nothing settles without it.

This is a coached self-quantification screen, never medical care, a fitness-for-duty call, or a diagnosis. Any red-flag symptom, such as new leg numbness or a recent back injury, routes out to a clinician instead of testing, and pain during a hold stops it immediately.

The full safety list for this job:

• Full red-flag list: current low-back pain of any intensity, radiating leg pain or numbness, a back injury within the past 6 weeks, unexplained weight loss, fever, saddle numbness, a new bowel or bladder change, prior spinal fracture or surgery, or uncontrolled disease.
• An endurance-ratio imbalance flags an elevated injury-risk pattern (McGill 1999), never a diagnosis, and a persistent imbalance despite training routes to a physical therapist.
• Results belong to the worker and are never shared with an employer.
• Any crisis or self-harm signal routes to the local crisis line or emergency services, and the agent screens and refers, never diagnoses or treats.
• This packet is independent of and not affiliated with Rigshospitalet or the University of Copenhagen, named as the real, verified current institution of this standard's own foundational citation's sole author, not an ongoing program this packet is part of.

Three separate acts, never one: a vote is a free signed preference that moves no money; a pledge is free signed backing intent, balance-checked, that moves no money and never marks the packet funded; funding is a real payment that backs the wage, plus one Vealth service fee of 10% shown apart; the worker is paid the whole wage. Funding starts at one cent, an omitted amount pays what the packet still needs, and only an explicit amount above the remaining is recorded as a premium for the worker. Money settles only on accepted proof. An agent can fund it in one x402 call: POST /nurture/fund {"workId":"WORK_1788978686612_be46qii","funderWallet":"0xYOU"}.

Claiming is free. You sign to prove the wallet is yours: no card, no deposit, no fee. Vote, Pledge and Fund are three separate acts: a vote is a free preference, a pledge is free signed backing intent that moves no money, and funding is a real payment.

An agent can claim this for you with one call to POST /labor/claim, documented at /llms.txt.

Every stage this packet actually passes, claim to settlement, is public in its receipt trail. A stage that has not happened is not claimed.

Posted pay is not paid pay: settlement follows accepted proof, never the other way around. Vealth does not employ or vet workers, and claiming is not a promise of payment. See how proof and receipts work.
